摘要 通过四步法制备了一系列具有立体结构的Pt/PPy/PS/Au电极。这种立体结构使液体醇燃料较容易扩散到催化剂层 ,降低了液封效应 ,从而使电化学反应的三相界面增大。与相同Pt载量的传统电极相比 。 A novel three-dimensional electrode structured by Pt/PPy/PS/Au was fabricated through four-step processes. The three-dimensional structure permited liquid alcohol to diffuse into the catalyst layer easier and resulted in large three-phase interface for electrochemical reactions due to the reduction of the liquid sealing effect.Preliminary study on the methanol oxidation indicated that the three-dimensional electrode could give a better electric performance for methanol oxidation than that of conventional electrode at the same catalysts loading.
